DThere have been reports that Covid-19 cases have been increasing for several weeks, among which people who have been fully vaccinated and are sick are increasingly causing people’s concern. vaccine And delta variants. Is the effect of the vaccine faster than expected? Is the Delta variant-or one of its descendants, has been discovered more than a dozen times-is it more dangerous than you think?
Recent survey by the U.S. Centers for Diseases CDC Data from Israel also shows that a third factor usually plays at least as important a role in breakthroughs in vaccination: one’s own behavior. Many vaccinated people obviously just feel too safe, and through close contact and lack of masks, the virus spreads quickly and effectively. Mass incidents are getting more and more attention.
In New York, scientists from the State University and the Department of Health evaluated adult immunization registries from early May to the end of July. As they now report online, vaccine breakthroughs mainly occurred in people between 18 and 49 years of age. People who are in close contact with many close contacts are obviously more likely to get sick if they ignore protective measures and exhibit dangerous behaviors. However, among vaccinators over 65 years of age in New York, no evidence of reduced vaccination effectiveness has been found so far.
Thousands of vaccines in Germany make breakthroughs
It can also be seen in Israel that the infection rate of vaccinated people between the ages of 20 and 49 has increased to such an extent that the effectiveness of the vaccinated people in this age group to prevent infection has dropped from more than 90% to about 30% -In addition to dangerous behaviors, this is only partly due to decreased immunity and Delta’s high infectivity.
Recently, an increasing number of young Covid-19 infected persons who have been previously vaccinated have been registered in hospitals, especially in the southern states of the United States, where the number of cases has increased exponentially. However, it is still unvaccinated people who are infected with Covid-19.In Germany it has Robert Koch Institute (RKI) has made thousands of breakthroughs in vaccination, and of course these breakthroughs are almost harmless. Severe course of disease is rarely found, especially in people with weakened immune function after vaccination. For them, many countries in the world have begun to vaccinate booster vaccines, including some German federal states.
Especially among those who have to ventilate or enter the intensive care unit, unvaccinated people account for the overwhelming majority-this shows that despite the more contagious delta spread, the Covid-19 vaccine is effective in preventing serious diseases Sexual variability is still high. These vaccines not only prevent the severe course of Covid-19, but also slow down the spread.
A Dutch preprint study of vaccinated but still infected clinic staff supports the suspicion that other studies have cultivated that vaccinated people contribute less to the spread of pathogens. All 161 vaccinated clinic employees have mild Covid-19. Viral kinetics measurements show that: infected vaccinated people can be infected in large numbers. Despite the presence of antibodies, the virus spreads in the mucous membranes in the first three days, leading to the initial symptoms of the disease. But after that, most can only find virus “fragments” and non-infectious genetic material in the nose and throat. The experiment of Dutch researchers trying to grow pathogenic materials in the laboratory proved this point.
The infectivity of vaccinated and unvaccinated people is only comparable at the beginning
The PCR test found in previous studies that in people who received breakthrough vaccines, virus levels were similar to those of unvaccinated people, which led some scientists to assume that vaccinated people and unvaccinated people have similarly high levels of infection sex. In fact, it confirmed a study published in the journal Science by a team of Charité virologists led by Christian Drosten: Comparable to people who have not been vaccinated. Once the immune response is fully activated and started through full vaccination, the vaccinated person poses less threat to others. However, Dutch doctors at Erasmus University advocate testing vaccinated people even if they have mild symptoms—especially if they work in a medical or aged care department, they can easily infect others.
However, the overall reduced infectivity of vaccination does not mean that this protection will remain unchanged in the long term. On the contrary: antibody levels will gradually decrease, because like all proteins, they will be broken down in the blood, even though this process occurs at different rates depending on vitality, previous disease, infection status, and age. Repeated contact during this period will naturally refresh the immune response triggered by the vaccine.
The decisive factor seems to be how much virus the vaccinated person has ingested. A large number of documents from various states in the United States indicate this. In Florida, the triangle wave has caused the intensive care unit of large hospitals in some areas to be completely occupied. Some reports confirming vaccine breakthroughs or simply spreading the virus to vaccinated people through large populations even mention outdoor activities, such as weddings and parties. In other words, the high viral load, weakened immunity, and risky behaviors from Delta further contributed to the pandemic—in this combination, confidence in the vaccine was unnecessarily weakened.
